The dude taking the vid. The belchers buddy. He cracks up every time his pal the mad burper starts to walk towards people. I made it for about 3 minutes but in almost every one - his pal starts to crack up before anything happens.

The problem with this if/when you dont expel all the air, you are going to be farting like crazy. So if you want to bother your wife, suck in a bunch of air, hold it in and let them rip like crazy in the evening. That should teach her a lesson or two about bothering you in the evening.
